How to write a layered drive (complex character driver)----LCD drive as an example **************Idea: Complex drivers are built on the basis of simple drives, so first know how the kernel simple character device driver writes1. How to simply drive a program1.1 Construction File_operations. open = Drv_open. Read = Drv_read1.2 Tell the kernel there are 1.1 this structure, Register_chrdev (main device number,

During the summer vacation, I made a project using SSH + mysql5.0 + atat5.5.After deployment to the server (Tomcat is 6.0.32), the test runs normally. The next day, I found that I could not log on. I checked the system and found no problems. I restarted Tomcat and recovered to normal again.Very strange, so I checked Tomcat logs and found the following problems: 2011-9-1 0:15:11 org. Apache.

This article is written in November 13, this is only a record of the knowledge that has been covered in this area, may be useful for some knowledge of the futureFor the platform bus model, you can refer to a previous article on the Linux driver platform bus model, which may be helpful for framebuffer driver registrationFirst, the LCD hardware frameworkSecond, LCD software frameworkThird, LCD initialization

From this blog post, we can finally give our driver module First_drv a formal compilation, now he has filled out his account registration information form, from the account of the child only one step!Inside the kernel has its own set of methods to install the driver module, like the Civil Affairs Bureau staff know how to run an account for a person, for an ordinary citizen, the staff did what the operation

1. Driver test of onboard buzzerI have a BSP, jiuding BSP, which has a buzzer driver, we first test it well. When we get a BSP, if we want to do or transplant the driver of the buzzer, first determine the next coreThere is no buzzer driver, we can use Sourceinsight to put the kernel in, search buzzer this file, see if

The Linux kernel is highly customizable and can be customized by configuring the compilation options.When configuring the kernel compilation option, there are generally three compiler options for the driver, not compiling, compiling kernel-driven, and compiling to module-driven. So Linux drivers are generally divided into two categories, kernel-driven and module-driven, of course, there is no absolute difference between the two; when compiled into ker

The driver wizard's friends know that the driver wizard is used to repair the computer hardware software, everyone in the internet when there is a computer network card driver display is "yellow exclamation mark", and then the Web page can not open, small series encountered such a situation, this time everyone first thought must be the NIC

Now, let's write our own first character device driver--light LEDs. (Imperfect, back to perfect) Hardware platform: Exynos4412 (FS4412) Writing the drive is divided into the following steps: A--View the schematic, data manual, understand the equipment operation method; B-Find a similar driver in the kernel, develop it as a template, and sometimes need to start from scratch; C-Implement
